“…Since to achieve good bacterial biomass quality as feed ingredient it is advisable to reach crude protein contents above 50 % DW, it is suggested to use the sludge as feedstock for anaerobic digestion instead. If a WRRF is still considering production of microbial protein, aerobic methanotrophs may be considered instead, which protein content is high (Khoshnevisan et al, 2022). They can be grown nutrients from digestate and methane from biogas.…”

“…However, other possible applications are emerging. Ammonia recovered from wastewater has been proposed as a nitrogen source for microbial protein production, replacing synthetic nitrogen and contributing to the sustainability of the process [ 91 ], or for growing bacteria or algae that could be used for the production of biogas or biofuels [ 92 ]. In this sense, more research is needed to fully characterise the concentrated solutions recovered from BESs before their reuse in agricultural soils since livestock manure, urine, and other wastewaters may contain significant concentrations of both inorganic (e.g., heavy metals) and organic contaminants (pesticides, herbicides, antibiotics, etc.)…”

Recent Advances in Bioelectrochemical Systems for Nitrogen and Phosphorus Recovery Using Membranes

2023

Bioelectrochemical systems (BESs) have emerged as a technology that is able to recover resources from different kinds of substrates, especially wastewater. Nutrient recovery, mostly based on membrane reactor configuration, is a clear niche for BES application. The recovery of nitrogen or phosphorus allows for treatment of wastewater while simultaneously collecting a concentrated stream with nutrients that can be reintroduced into the system, becoming a circular economy solution. The aim of this study is to review recent advances in membrane-based BESs for nitrogen and phosphorus recovery and compare the recovery efficiencies and energy requirements of each system. Finally, there is a discussion of the main issues that arise from using membrane-based BESs. The results presented in this review show that it would be beneficial to intensify research on BESs to improve recovery efficiencies at the lowest construction cost in order to take the final step towards scaling up and commercialising this technology.

“…Obviously, if at least some of this energy can be imparted to the plants, this will significantly increase yields. At the moment, conversion of solar energy to proteins appears even more realistic [129].…”

Agrivoltaics (Agri-PV, AV) – the joint use of land for the production of agricultural products and energy – has recently been rapidly gaining popularity, as it can significantly increase income per unit of land area. In a broad sense, AV systems can include converters of not only solar, but also energy from any other local renewable source, including bioenergy. Current approach to AV represents an evolutionary development of agroecology and integrated PV power supply to the grid. That results in nearly doubled income per unit area. While AV could provide a basis for revolution in large-scale unmanned precision agriculture and smart farming which is impossible without on-site power supply, chemical fertilisation and pesticides reduction, and yield processing on-site. These approaches could change the logistics and the added value production chain in agriculture dramatically, and so, reduce its carbon footprint. Utilisation of decommissioned solar panels in AV could make the technology twice cheaper and postpone the need for bulk PV recycling. Unlike the mainstream discourse on the topic, this review feature is in focusing on the possibilities for AV to be stronger integrated into agriculture that could also help in relevant legal collisions (considered as neither rather than both components) resolution.
